This paper describes the design, implementation, and usage of an "IOS236 installer" for the Wii console. The installer provides a method to install or restore IOS36 and associated modules to enable homebrew applications and compatibility patches. It covers the installer architecture, safety checks, installation workflow, filesystem and network considerations, failure recovery, and security implications.
While the Wii is considered a "dead" console by commercial standards, the homebrew community is more alive than ever, preserved by digital archivists.
